Description

The clamping of moulding machine
Technical field
The present invention relates to a kind of clamping of moulding machine.
Background technology
Moulding machine (for example injector) is gone up traditional clamping and is generally comprised stationary platen and end frame (being also referred to as end plate), and the both is vertically mounted on the base of moulding machine; A plurality of (normally four) play the connecting rod of bridging effect between stationary platen and end frame; But have a plurality of through hole of each connecting rod and dynamic pressure plates of settling movably along the connecting rod between stationary platen and the end frame accepted respectively; But and the driver element (for example toggle unit (toggle unit)) that is used to drive dynamic pressure plate.But but a dynamic model and has a stationary mold attached on the stationary platen attached on the dynamic pressure plate.Comprise that but motor or cylinder and so on drive source drives unit moves dynamic pressure plate under the guiding of connecting rod, thereby two moulds are closed up.In general, a pair of sliding bearing sleeve is arranged, and every connecting rod slides and passes described bearing holder (housing, cover) but be formed in each through hole on the dynamic pressure plate.
In aforesaid traditional clamping; but the sliding bearing structure that is used in the mutual slipper between dynamic pressure plate and the every connecting rod can produce the gap inevitably between the external peripheral surface of the inner circumferential surface of bearing holder (housing, cover) and connecting rod, this can cause the loosening of sliding bearing.Therefore, but dynamic pressure plate in the move operation process, be easy to tilt at connecting rod.Therefore, but but but might be damaged because of the move operation of dynamic pressure plate attached to the dynamic model on the dynamic pressure plate with attached to the depth of parallelism predetermined between the stationary mold on the stationary platen.For example, in the die sinking process, if but the collimation between two moulds separate in dynamic model and stationary mold and cause that the moment of the demoulding is damaged, but the demoulding some some place on the molded surface of stationary mold or dynamic model on opportunity of moldings can become irregular so.When molded high accuracy moldings such as lens, the irregular meeting on demoulding opportunity produces strain because of tensile stress etc. on moldings, thereby may produce defective moldings.
In order to address the above problem; known solution is: linear guides (commodity are called the LM guide rail) is positioned on the base of moulding machine; but be used to guide the operation of dynamic pressure plate, but can prevent that therefore dynamic pressure plate from tilting, but and the collimation between maintenance dynamic pressure plate and the stationary platen.In adopting the solution of linear guides, but the bottom of dynamic pressure plate is subjected to the supporting of linear guides, but therefore the inclination of dynamic pressure plate bottom is suppressed, but but is difficult to suppress the inclination on dynamic pressure plate top.In addition, but but linear guides can prevent dynamic pressure plate around axle along the moving direction of dynamic pressure plate (connecting rod axially) in other words rotation, but but linear guides is difficult to prevent that dynamic pressure plate from winding perpendicular to above-mentioned axis and be parallel to another root axis rotation of the mould attaching surface of this pressing plate.
On the other hand, in the matched moulds process, but stationary platen and/or dynamic pressure plate owing to be applied to that but mutual pressure can deform or strain on the static and dynamic model.If but stationary platen and/or dynamic pressure plate generation strain, the mould attaching surface of this pressing plate can deform so, but this also can cause the collimation between static and the dynamic model destroyed, thereby makes molded precision destroyed.
As preventing strain on the pressing plate or a solution of distortion; for example; Japanese Utility Model discloses the clamping that No. 2587035 (JP2587035) discloses a kind of injector; wherein but at least one is provided at the centre position of seeing along the thickness of compressive plate direction in stationary platen and the dynamic pressure plate; in the zone of the connecting rod patchhole on being formed on four angles of this pressing plate, and there be one groove to extend in this connecting rod patchhole from the external peripheral surface of this pressing plate.According to this scheme, be applied to two pressure loadings on the mould by the absorption of the distortion in this pressing plate grooved area, thereby prevented the distortion on this pressing plate mould attaching surface.
In addition, Japanese unexamined patent publication No. open (kokai) No.8-258103 (JP8-258103A) discloses a kind of clamping of injector, and wherein the supporting structure of stationary platen forms the taper of rectangular pyramid or frustum of a cone and so on.According to this scheme, prevented the pressure loading that produces during the die sinking because taper bending moment effect on supporting structure of the latter, thereby prevented deflection or distortion on supporting structure and the stationary platen.
In addition; open (kokai) No.11-170322 (JP11-170322A) of Japanese unexamined patent publication No. discloses a kind of clamping of injector, but is wherein providing an anti-Response Division (for example transverse side groove) on the dynamic pressure plate between the pivot arm of toggle mechanism and mould attaching surface.According to this scheme, but produce during the matched moulds pressure loading absorbed by the distortion of the anti-Response Division of dynamic pressure plate, thereby prevent the distortion of mould attaching surface.
In above-mentioned traditional technology, the structure that absorbs the pressure loading that is produced in the matched moulds process is provided on pressing plate or supporting structure, strain takes place to prevent pressing plate (especially in the matched moulds process).By contrast, the open No.3330578 (JP3330578B2) of Japan Patent discloses the clamping of a kind of moulding machine such as injector, but wherein is used for the guide portion employing ball spline structure replacement sliding bearing structure of guiding dynamic pressure plate on connecting rod.According to this scheme, but the guide portion with ball spline structure might make dynamic pressure plate always with respect to the accurate translation of stationary platen (carrying out translation in other words), but so can stably keep collimation between stationary mold and the dynamic model in the die sinking process.In this scheme, it is to be noted that the life-span of ball spline structure is long, even in the matched moulds process owing to pressure loading is subjected to the pressing plate stress influence.

The specific embodiment
Describe various embodiments of the present invention with reference to the accompanying drawings in detail.In the accompanying drawings, same or analogous parts are represented with identical Reference numeral.
The basic conception of the clamping of moulding machine comprises first pattern and second pattern as described in the present invention.In first pattern, but the dynamic pressure plate (but being called second dynamic pressure plate in this application) that auxiliary dynamic pressure plate (but being called first dynamic pressure plate in this application) but be placed in is connected on the drive part but and between the dynamic model, but and the guiding/supporting structure of ball spline structure as first dynamic pressure plate be provided; In second pattern, but first and second dynamic pressure plates be meshing with each other by connector, can guarantee simultaneously certain clearance displacement mutually in other words.According to above-mentioned notion, but can keep carrying the fixation clip of mould and the collimation between first dynamic pressure plate respectively, and can avoid the life-span of ball spline to shorten along the axial distribution of ball spline nuts is inhomogeneous because of load.
With reference to accompanying drawing, Fig. 1 and 2 shows the clamping 10 of the described moulding machine of first embodiment of realizing the present invention's first notion.Clamping 10 comprises base 12; Be installed on the base 12 and be used to carry the stationary platen 14 of stationary mold 16; Guide post 18 with respect to stationary platen 14 fixed in position and qualification longitudinally guiding axle 18a; But but can move and carry first dynamic pressure plate 20 of dynamic model 22 along axis of guide 18a with respect to stationary platen 14; But be inserted between the guide post 18 and first dynamic pressure plate 20 and but first dynamic pressure plate 20 is bearing in supporting structure 24 on the guide post 18 movably along axis of guide 18a; But one second dynamic pressure plate 26, but its separate with first dynamic pressure plate 20, and can settle movably along axis of guide 18a with respect to stationary platen 14; But but with first dynamic pressure plate 20 and second dynamic pressure plate, 26 connectors 28 connected to one another; Thereby but but but be used for driving force is applied to the drive part 30 that first dynamic pressure plate 20 and second dynamic pressure plate 26 are moved along axis of guide 18a.Described clamping 10 also comprises the end frame 32 that is installed on the base 12, but end frame 32 is in about the relative position of first and second dynamic pressure plates 20,26 and stationary platen 14.
Guide post 18 is configured to stationary platen 14 and end frame 32 interconnective connecting rods 18.In embodiment as shown in the figure, stationary part 14 is rectangle with end frame 32 perpendicular to two relative surfaces of base 12, and four connecting rods 18 are placed in apparent surface four jiaos (Fig. 1 has only provided two connecting rods 18) respectively.
One end of every connecting rod 18 is fastened on the stationary platen 14 by the tightening member of nut and so on, and the adjusting nut 34 of its other end by regulating mold thickness is connected on the end frame 32 in mode relatively movably.Pinion 36 is fastened to respectively on the adjusting nut 34 of regulating mold thickness, and a chain (not shown) is wrapped in and lays respectively on four pinions 36 on the connecting rod 18.When described chain drove with the adjusting mold thickness by the drive source that does not show and makes nut 34 rotation synchronously of connecting rod 18, end frame 32 moved along connecting rod 18 at base 12.Therefore, the distance between end frame 32 and the stationary platen 14 can be regulated, and therefore also can regulate clamping force, and this depends on the thickness of mould therefor.
Every connecting rod (guide post) but but 18 be received in the through hole that is formed on first dynamic pressure plate 20 and second dynamic pressure plate 26 in mode relatively movably, and be in alignment with each other along axis of guide 18a.Every connecting rod 18 has spline engagement surface 38, and described spline engagement surface 38 is extended and the flange or the groove that are positioned at least on the predetermined surface zone form along axis of guide 18a by a plurality of, but first dynamic pressure plate 20 slides thereon along connecting rod 18.In other words, the effect of connecting rod 18 is equivalent to have the splined shaft on the described zone on spline engagement surface 38.On the other hand, but being used on first dynamic pressure plate 20 receive each through hole of connecting rod 18 have can with the ball spline nuts 40 of the spline engagement of connecting rod 18 surface 38 engagements.But corresponding ball spline nuts 40 cooperatively interacts to constitute supporting structure 24 on 38 and first dynamic pressure plate 20 of the spline engagement of connecting rod 18 surface.In embodiment as shown in the figure, but a pair of ball spline nuts 40 is arranged in each through hole of first dynamic pressure plate 20.
By contrast, but each through hole that is used to receive connecting rod 18 on second dynamic pressure plate 26 has a sliding bearing sleeve 42, sliding bearing sleeve 42 can not with spline engagement surface 38 engagements on the connecting rod 18.Each sliding bearing sleeve 42 receives corresponding connecting rod 18 slidably by gap small between it and the corresponding connecting rod 18, thereby but second dynamic pressure plate 26 is moved along axis of guide 18a.In embodiment as shown in the figure, but each through hole on second dynamic pressure plate 26 has a pair of sliding bearing sleeve 42.In addition, also can be without sliding bearing sleeve 42, but the internal diameter of each through hole that can select second dynamic pressure plate 26 on the contrary greater than the external diameter of connecting rod 18, but therefore the through hole of second dynamic pressure plate 26 can receive connecting rod 18 in the noncontact mode.
Connector 28 is formed by the tightening member of bolt and so on, but but and the position of connector 28 with first dynamic pressure plate, 20 localized immobilization to the second dynamic pressure plates 26 on.In embodiment as shown in the figure, but two connectors 28 are provided in position near each dynamic pressure plate 20,26 center.But when dynamic pressure plate 20,26 deflections, but the localized immobilization of connector 28 is used to allow the adjacently situated surfaces of dynamic pressure plate 20,26 to slide relatively slightly.
But drive part 30 comprises the toggle unit 44 between end frame 32 and second dynamic pressure plate 26, and the drive source 46 of servomotor and so on, and drive source 46 is used to drive the crosshead 44a of toggle unit 44.Toggle unit 44 and drive source 46 are installed on the end frame 32, but the end of a pair of arm 44b of toggle unit 44 is connected respectively to the top and the bottom section of second dynamic pressure plate 26.
But but stationary mold 16 and dynamic model 22 are respectively on relative mould attaching surface 14a, the 20a attached to the stationary platen 14 and first dynamic pressure plate 20.When starting drive source 46 driving toggle unit 44, thereby but but second dynamic pressure plate 26 and first dynamic pressure plate 20 are moved along the direction of connecting rod 18 along axis of guide 18a, mould 16,22 is opened under handling or closed (die sinking or matched moulds operation).
Fig. 2 illustrates the matched moulds state.Under the effect of the clamping force that drive part 30 is applied, but second dynamic pressure plate 26 and stationary platen 14 slight deformation are shown in dotted line.In this case, but owing to second dynamic pressure plate 26 is directly connected on the toggle unit 44, so its strain is bigger with distortion.By contrast, because but first dynamic pressure plate 20 is not directly connected on the toggle unit 44, and but second dynamic pressure plate 26 is positioned between the two, but therefore by means of the slight slip between the adjacently situated surfaces of described dynamic pressure plate 20,26, but the strain of first dynamic pressure plate 20 and distortion reduce.Therefore, during matched moulds, but the strain of the mould attaching surface 20a of first dynamic pressure plate 20 be suppressed, like this, but just might prevent that the collimation between mould attaching surface 14a, the 20a of the stationary platen 14 and first dynamic pressure plate 20 is destroyed.
In addition, but when stationary mold 16 does not contact during die sinking with dynamic model 22, be easy to be subjected to the influence of the production error of toggle mechanism and/or its gravity and deform or strain but be connected to second dynamic pressure plate 26 on the toggle unit 44.According to clamping 10; during being in die opening state; might prevent that also but but the strain in second dynamic pressure plate 26 is passed to first dynamic pressure plate 20, thereby but but collimation between mould attaching surface 14a, the 20a of the maintenance stationary platen 14 and first dynamic pressure plate 20 and the collimation between stationary mold 16 and the dynamic model 22.
Equally, in clamping 10, but the supporting structure 24 between first dynamic pressure plate 20 and the connecting rod (or claiming guide post) 18 is made of described ball spline structure.In common ball spline structure, almost very close to each other between splined shaft and the ball spline nuts, this is because there is the spline engagement surface (for example ball rolling groove) of a large amount of balls and splined shaft to mesh under certain pressure.But the supporting structure 24 that adopts this ball spline structure is used for fully eliminating the gap between the connecting rod 18 and first dynamic pressure plate 20.
And, in embodiment as shown in the figure, surpass splined shaft length (the spline engagement surface 38 in other words) but connecting rod 18 be received in the ball spline nuts 40 at four angles that are positioned at first dynamic pressure plate 20, but might prevent effectively that therefore first dynamic pressure plate 20 from tilting.In other words, but first dynamic pressure plate 20 is limited on four connecting rods 18 by the ball spline structure, but this might make first dynamic pressure plate 20 with respect to stationary platen 14 accurately translation always (carrying out translation in other words), and can not cause that but first dynamic pressure plate about axis of guide 18a rotation, can not rotate respectively about vertical axis and the horizontal axis perpendicular to axis of guide 18a yet.Should be pointed out that the inhibition effect of not only using the above-mentioned configuration that four connecting rods 18 are arranged to obtain this rotation, and use other configurations that have two connecting rods 18 (being positioned on the diagonal) at least also can obtain the inhibition effect of this rotation.
Therefore, but mould attaching surface 14a, the 20a of the stationary platen 14 and first dynamic pressure plate 20 always (are included under matched moulds and the die opening state) keeping parallelism, but and also remain in suitable position relation attached to the molded surface of the static and dynamic model 16,22 on mould attaching surface 14a, the 20a respectively.Especially in demoulding step, might prevent effectively that the demoulding some some place on molded surface on opportunity of moldings is irregular.Therefore, guarantee to prevent that moldings is subjected to because of the demoulding irregular or inhomogeneous strain that causes on opportunity, so just might produce the high accuracy goods of lens and so on extremely beneficially.
In addition, except being provided for the above-mentioned ball spline structure of supporting structure 24, said, but but the strain on first dynamic pressure plate 20 of carrying dynamic model 22 do not reduce because but first dynamic pressure plate 20 is not directly connected on the toggle unit 44, therefore might eliminate following shortcoming: but the ball spline nuts 40 that is arranged on first dynamic pressure plate 20 contacts with the spline engagement surface 38 of corresponding connecting rod 18 along axis of guide 18a skewness because of load.As a result, might prolong the spline engagement surface 38 of connecting rod 18 and the life-span of ball spline nuts 40 greatly.
In above-mentioned configuration, but interconnective first and second dynamic pressure plates 20,26 can be with different material manufacturings.Especially advantageously, but but the rigidity that is used to make the material of first dynamic pressure plate 20 is higher than the rigidity of second dynamic pressure plate, 26 materials.Thus, the material stiffness higher position means material elastic modelling quantity is big longitudinally.For example, but when second dynamic pressure plate, 26 usefulness casting pig or spheroidal graphite cast-iron manufacturing, but dynamic pressure plate 20 can approximately be the material manufacturing of the twice of preceding a kind of material with longitudinal modulus of elasticity, for example used used carbon steel or the used steel alloy of universal architecture of steel rolling, universal architecture of universal architecture.
For example, owing to provide the toggle unit 44 that is attached thereto, but so structure relative complex of second dynamic pressure plate 26.Therefore in general, the material of rigidity height (longitudinal modulus of elasticity is big in other words) is difficult to processing, and this can increase production cost, but low to be convenient to cast material processed manufacturing second dynamic pressure plate 26 be favourable with rigidity.On the other hand, but the structure of first dynamic pressure plate 20 is simple relatively, and does not need complicated processing.Therefore, but first dynamic pressure plate 20 can be used the high material manufacturing of rigidity, and can not increase production cost.Therefore, but might further effectively reduce strain on first dynamic pressure plate 20, might stablize the collimation that keeps between static and the dynamic model 16,22 but this makes, thereby prolong the life-span of ball spline structure.
It is pointed out that in the above-described embodiments, but the number that is provided at the ball spline nuts 40 in each connecting rod receiving through-hole of first dynamic pressure plate 20 is not limited to two shown in the figure, can be one or three or more.Because the ball spline length of action for example because of the increase of ball spline nuts 40 numbers increases, suppress the effect that first dynamic pressure plate 20 tilts or rotates but therefore improved, but this has further been stablized the translation translation in other words of first dynamic pressure plate 20.
In addition, but first and second dynamic pressure plates 20,26 can be installed on the base 12 by known platen support 48 (Fig. 1), but therefore can actively regulate the inclinations of dynamic pressure plates 20,26 with platen support 48.The structure of platen support 48 can as for example awarded on July 4th, 1972 people's such as Sauerbruch U.S. Patent No. 3674400 disclosed, the instruction of this article is merged in this and sentences for referencial use.
Fig. 3 shows the described clamping 50 as second embodiment that realizes first notion of the present invention.Except the guide post and the connecting rod that are separated from each other and the ball spline structure that only is used for guide post, the configuration of the clamping 50 of second embodiment and the clamping 10 of first embodiment basic identical.Therefore, corresponding parts are represented with identical Reference numeral, and the description of detail also no longer repeats.
Clamping 50 comprises with respect to the guide post 18 of stationary platen 14 fixed in position, the connecting rod 52 that has the ball spline structure and along the axis of guide 18a of guide post 18 but first dynamic pressure plate 20 is bearing in the supporting structure 24 on the guide post 18 movably and is different from guide post 18.Connecting rod 52 limits and generally is parallel to the second longitudinally guiding axle 52a of axis of guide 18a, and interconnects stationary platen 14 and end frame 32.
In embodiment as shown in the figure, the apparent surface of stationary platen 14 and end frame 32 is rectangular, and has four connecting rods 52 to be installed in respectively on four angles of apparent surface.Identical with the connecting rod 18 among first embodiment, an end of every connecting rod 52 is fastened on the stationary platen 14, its other end by mold thickness adjusting nut 34 with relatively-movable mode attached to the end frame 32 on.Two guide posts 18 are placed in the outside of a pair of connecting rod of settling along diagonal 52 respectively.One end of every guide post 18 is fastened on extending laterally on the part 14b of stationary platen 14, and its other end is bearing in extending laterally on the part 32a of end frame 32 slidably.
But every guide post 18 is received in mode relatively movably and is formed on the extending laterally in the through hole on the part 20b of first dynamic pressure plate 20.Every guide post 18 all has by a plurality of and extends and be positioned at the spline engagement surface 38 that flange on the predetermined surf zone or groove form at least along axis of guide 18a, but first dynamic pressure plate 20 slides thereon along guide post 18.In other words, the effect of guide post 18 is equivalent to have the splined shaft on the described zone on spline engagement surface 38.On the other hand, shown in Fig. 4 A and 4B, the ball spline nuts 40 that can mesh with the spline engagement surperficial 38 of guide post 18 is all arranged but being used on first dynamic pressure plate 20 receives each through hole band of guide post 18.But corresponding ball spline nuts 40 cooperatively interacts to constitute supporting structure 24 on 38 and first dynamic pressure plate 20 of the spline engagement of guide post 18 surface.In embodiment as shown in the figure, but a pair of ball spline nuts 40 is arranged in each through hole of first dynamic pressure plate 20.
But but every connecting rod 52 be received in the through hole that is formed on first dynamic pressure plate 20 and second dynamic pressure plate 26 in mode relatively movably, and be in alignment with each other along axis of guide 52a.Every connecting rod 52 all is a rod-shaped elements, has smooth basically external peripheral surface.Shown in Fig. 4 A and 4B, but each through hole that is used to receive connecting rod 52 on second dynamic pressure plate 26 has sliding bearing sleeve 42, and this is identical with first embodiment.Each sliding bearing sleeve 42 receives corresponding connecting rod 52 slidably by gap small between it and the corresponding connecting rod 52, thereby but second dynamic pressure plate 26 is moved along axis of guide 52a.On the other hand, but first dynamic pressure plate 20 in non-contacting mode connecting rod 52 is received in separately the through hole 54, the internal diameter of each through hole 54 is greater than the external diameter of connecting rod 52.
Like this; in clamping 50; but first dynamic pressure plate 20 is bearing on the guide post 18 by the supporting structure 24 with ball spline structure; and but second dynamic pressure plate 26 is by sliding bearing sleeve 42 and connecting rod 52 engagements, but and the driving of drive part 30 operation two dynamic pressure plates 20,26 are moved along axis of guide 18a (52a).Be understood that to have characteristic effect that the clamping 50 of above-mentioned configuration had identical with the clamping 10 of first embodiment basically.In addition, in clamping 50, guide post 18 is independent of connecting rod 52 and provides, so the effect (but in order to keep the collimation of first dynamic pressure plate 20) of guide post 18 and the supporting structure 24 with ball spline structure is affected because of separating with connecting rod 52.Therefore, might prevent that but strain or distortion on the connecting rod 52 are passed to first dynamic pressure plate 20, strain on the connecting rod 52 or distortion come from the stress that is for example caused by drive part 30, but suppress the effect that first dynamic pressure plate 20 tilts or rotates thereby improve, but this has further stablized the translation translation in other words of first dynamic pressure plate 20.And, also might prolong the life-span of ball spline structure.
In embodiment as shown in the figure, although used two guide posts of settling along diagonal 18, the present invention is not limited thereto, also can use other guide posts 18 of settling along another diagonal.In this device, but ball spline nuts 40 also is provided at other two angles of first dynamic pressure plate 20, shown in the dotted line among Fig. 4 B.In addition, guide post 18 also is not limited to the structure that plays the connection effect between stationary platen 14 and end frame 32 as shown in the figure, and it can separate with stationary platen 14 and end frame 32 provides.
Although the various embodiments described above concentrate on the configuration that drive part 30 adopts toggle unit 44; but peculiar configuration of the present invention also can be applicable to comprise the clamping of direct pressurised driving part; in direct pressurised driving part; but first and second dynamic pressure plates 20,26 are directly driven by the drive source 46 of cylinder or servomotor and so on, and do not use toggle unit 44.Be understood that, in this configuration, also can obtain with each embodiment in the characteristic effect of characteristic effect equivalence.
Fig. 5 A-7 shows the described clamping 60 of the 3rd embodiment of realizing second notion of the present invention.But constitute by sliding bearing structure and but first and second dynamic pressure plates interconnected slidably by connector, the configuration of the configuration of the clamping 60 of the 3rd embodiment and the clamping 10 of first embodiment was basic identical except the supporting structure that supports first dynamic pressure plate.Therefore, corresponding parts are represented with identical Reference numeral, and detail is described also no longer repetition.
Clamping 60 comprises the stationary platen 14 that is installed on the base 12; But first dynamic pressure plate 20 that can settle movably along the axis of guide 18a of guide post 18 with respect to stationary platen 14; Have sliding bearing structure and but first dynamic pressure plate 20 is bearing in supporting structure 24 on the guide post 18 movably along axis of guide 18a; But but second dynamic pressure plate 26 that separates with first dynamic pressure plate 20 and can settle movably along axis of guide 18a with respect to stationary platen 14; But but and to interconnect the connector 28 (Fig. 6) of first dynamic pressure plate 20 and second dynamic pressure plate 26 along the relatively-movable mode of axis of guide 18a.
As shown in Figure 6, the guide post 18 in the clamping 60 structurally is a connecting rod 18 that stationary platen 14 and end frame 32 are connected with each other.In embodiment as shown in the figure, the apparent surface of stationary platen 14 and end frame 32 is rectangular, and has four connecting rods 18 to be placed in respectively on four angles of apparent surface.But but every connecting rod 18 be received in the through hole that is formed on first dynamic pressure plate 20 and second dynamic pressure plate 26 in mode relatively movably, and be in alignment with each other along axis of guide 18a.Every connecting rod 18 all is a rod-shaped elements, has smooth basically external peripheral surface.But each through hole that is used to receive connecting rod 18 on first and second dynamic pressure plates 20,26 has a sliding bearing sleeve 42.Each sliding bearing sleeve 42 receives corresponding connecting rod 18 slidably by gap small between it and the corresponding connecting rod 18, thereby but first and second dynamic pressure plates 20,26 is moved along axis of guide 18a.Like this, in clamping 60, but the supporting structure 24 and connecting rod 18 engagements of first and second dynamic pressure plates 20,26 by having sliding bearing structure, and the driving of drive part 30 operation makes it to move along axis of guide 18a.
Shown in Fig. 5 A and 5B, connector 28 is made of the tightening member of bolt with expansion-head 28a and bar 28b and so on, but and with mutually movably mode in the position of connector 28 but first dynamic pressure plate, 20 parts are connected on second dynamic pressure plate 26.In embodiment as shown in the figure, but two connectors 28 (Fig. 6) are provided in position near each dynamic pressure plate 20,26 center.
But the bar 28b of each connector 28 end is secured on second dynamic pressure plate 26, but it other end that comprises expansion-head 28a with along axis of guide 18a movably mode be attached on first dynamic pressure plate 20 (Fig. 6).In order to ensure this relative displacement (for example " becoming flexible "), but have staged through hole 62 on first dynamic pressure plate 20, each through hole with vertically movably mode receive the expansion-head 28a and the bar 28b of connector 28, and parallel with the axis of guide 18a of connecting rod 18.Each staged through hole 62 comprises expansion-head 28a and the bigger 62a of hole portion and the bar 28b and the less 62b of hole portion of diameter that are used to receive connector 28 of diameter that is used to receive connector 28.But the axial length of the 62a of hole portion that the diameter of staged through hole 62 is bigger is got the relative displacement distance of piece in the first and second required dynamic pressure plates 20,26.Preferably, the diameter of the 62a of hole portion that diameter is bigger allows the expansion-head 28a of connector 28 to be received in wherein, and is limited with enough gaps between the two.In addition, the diameter of the 62d of hole portion that preferred diameter is less allows the bar 28b of connector 28 to be received in wherein, and is limited with small gap between the two.Certainly, the less 62d of hole portion of diameter can slidably receive bar 28b.
But but Fig. 5 A has illustrated second dynamic pressure plate 26 and first dynamic pressure plate, 20 tight state of contact (corresponding with matched moulds state shown in Figure 6), but but Fig. 5 B has illustrated the state (corresponding with die opening state shown in Figure 7) that second dynamic pressure plate 26 and first dynamic pressure plate 20 separate.In the state of Fig. 5 B, but the expansion-head 28a of connector 28 leans against on the shoulder face 62C of the less 62b of the hole portion intersection of the bigger 62a of hole portion of the diameter of the staged through hole 62 on first dynamic pressure plate 20 and diameter, but but therefore the distance between second dynamic pressure plate 26 and first dynamic pressure plate 20 can not surpass predetermined mutual shift length.
With reference to Fig. 7, but but when driving toggle unit 44 so that second dynamic pressure plate 26 and first dynamic pressure plate 20 along die sinking direction (shown in arrow α) when mobile, but second dynamic pressure plate 26 at first begins to move towards end frame 32.Thus, but first dynamic pressure plate 20 by " gap " that obtain by connector 28 but be connected on second dynamic pressure plate 26, and keep static, but up to second dynamic pressure plate 26 move with described " gap " corresponding distance till.When but the distance that moves when second dynamic pressure plate 26 surpasses described " gap ", but 20 beginnings of first dynamic pressure plate move towards end frame 32, be subjected to the promotion of connector 28 simultaneously, thereby mould 16,22 opened.
Therefore, during die sinking---but stationary mold 16 does not contact with dynamic model 22, but second dynamic pressure plate 26 on being connected to toggle unit 44 is owing to for example weight of toggle unit 44 takes place by as shown in phantom in Figure 7 strain or when distortion, work in " gap " between corresponding connector 28 and the staged through hole 62, but to absorb this strain on second dynamic pressure plate 26.The result is, but first dynamic pressure plate 20 can translation or translation, but and can not be subjected to the influence of the strain on second dynamic pressure plate 26, but but so the collimation between the mould attaching surface 14a of the stationary platen 14 and first dynamic pressure plate 20 and the collimation between the 20a and stationary mold 16 and the dynamic model 22 just kept.
But first and second dynamic pressure plates 20,26 can be opposite with embodiment as shown in the figure with relation between the connector 28.In other words, each connector can be designed to following structure: but its bar 28b end is secured on first dynamic pressure plate 20, and it comprises that but the other end of expansion-head 28b is received in the staged through hole (not shown) that is formed on second dynamic pressure plate 26, thereby but in mode that can displacement along axis of guide 18a attached on second dynamic pressure plate 26.
Fig. 8 and 9 has provided the described clamping 70 of the 4th embodiment that realizes second notion of the present invention, is in matched moulds and die opening state respectively.Except but the supporting structure that supports first dynamic pressure plate is formed by the ball spline structure, the configuration of the clamping 70 of the 4th embodiment and the clamping 60 of the 3rd embodiment basic identical.Therefore, corresponding parts are represented with identical Reference numeral, and detail is described also no longer repetition.
Clamping 70 comprises the stationary platen 14 that is installed on the base 12; But first dynamic pressure plate 20 that can settle movably along the axis of guide 18a of guide post 18 with respect to stationary platen 14; Have the ball spline structure and but first dynamic pressure plate 20 is bearing in supporting structure 24 on the guide post 18 movably along axis of guide 18a; But but second dynamic pressure plate 26 that separates with first dynamic pressure plate 20 and can settle movably along axis of guide 18a with respect to stationary platen 14; But but and to interconnect the connector 28 of first dynamic pressure plate 20 and second dynamic pressure plate 26 along the relatively-movable mode of axis of guide 18a.
The supporting structure with ball spline structure 24 in the clamping 70 is identical with supporting structure (Fig. 1) among first embodiment.Like this, guide post 18 structurally is a connecting rod 18, stationary platen 14 and end frame 32 are connected to each other, and each root in four connecting rods 18 all has spline engagement surface 38 at least on predetermined surf zone, but first dynamic pressure plate 20 slides thereon along connecting rod 18.On the other hand, but being used on first dynamic pressure plate 20 receive each through hole of connecting rod 18 have can with the ball spline nuts 40 of the spline engagement of connecting rod 18 surface 38 engagements.By contrast, but each through hole that is used to receive connecting rod 18 on second dynamic pressure plate 26 all have one can not with the sliding bearing sleeve 42 of spline engagement surface 38 engagements on the connecting rod 18.
Connector 28 is identical with connector 28 among the 3rd embodiment, but and provides two connectors 28 in the position near each dynamic pressure plate 20,26 center.The bar 28b of each connector 28 holds (Fig. 5 A) but is secured on second dynamic pressure plate 26, it comprise expansion-head 28a (Fig. 5 A) but the other end be received in the staged through hole 62 of first dynamic pressure plate 20, but so it with along axis of guide 18a movably mode be attached on first dynamic pressure plate 20 (Fig. 8).
With reference to Fig. 9, but but when driving toggle unit 44 so that second dynamic pressure plate 26 and first dynamic pressure plate 20 along die sinking direction (shown in arrow α) when mobile, but second dynamic pressure plate 26 at first begins to move towards end frame 32 along connecting rod 18 under the supporting of sliding bearing structure.Thus, but first dynamic pressure plate 20 by " become flexible " of obtaining by connector 28 but be connected on second dynamic pressure plate 26, and keep static, but up to second dynamic pressure plate 26 move with described " become flexible " accordingly apart from till.When but the distance that moves when second dynamic pressure plate 26 surpasses described " becoming flexible ", but first dynamic pressure plate 20 moves towards end frame 32 in 18 beginnings of the supporting lower edge of the supporting structure 24 with ball spline structure connecting rod, also be subjected to the promotion of connector 28 simultaneously, thereby mould 17,22 is opened.
Be understood that to have characteristic effect that the clamping 70 of above-mentioned configuration had identical with the clamping 60 of the 3rd embodiment basically.In addition; in clamping 70; but the supporting structure 24 that is used for first dynamic pressure plate 20 adopts the ball spline structures, but but therefore might keep the collimation of mould attaching surface 14a, 20a of the stationary platen 14 and first dynamic pressure plate 20 and the collimation between stationary mold 16 and the dynamic model 22.And, but therefore translation might prolong the life-span of ball spline structure greatly but connector 28 is used to the influence that allows first dynamic pressure plate 20 not to be subjected to the strain on second dynamic pressure plate 26.
Figure 10 and 11 has provided the described clamping 80 of the 5th embodiment that realizes second notion of the present invention, is respectively matched moulds state and die opening state.Except have with connecting rod that guide post separates, the configuration of the clamping 80 of the 5th embodiment and the clamping 70 of the 4th embodiment basic identical.Therefore, corresponding parts are represented with identical Reference numeral, and the description of detail also no longer repeats.
Clamping 80 comprises the guide post 18 with respect to stationary platen 14 fixed in position; Have the ball spline structure and but first dynamic pressure plate 20 is bearing in supporting structure 24 on the guide post 18 movably along the axis of guide 18a of guide post 18; With the connecting rod 52 that guide post 18 separates, it limits and generally is parallel to the second longitudinally guiding axle 52a of axis of guide 18a and interconnects stationary platen 14 and end frame 32; But but and to interconnect the connector 28 of first dynamic pressure plate 20 and second dynamic pressure plate 26 along the relative movably mode of axis of guide 18a.
The supporting structure with ball spline structure 24 in the clamping 80 is identical with supporting structure 24 (Fig. 3) among second embodiment.Like this, on predetermined surf zone, all have spline engagement surface 38 at least along each root in two guide posts 18 of diagonal arrangement, but first dynamic pressure plate 20 slides thereon along guide post 18.On the other hand, but being used on first dynamic pressure plate 20 receive each through hole of guide post 18 have can with the ball spline nuts 40 of the spline engagement of guide post 18 surface 38 engagements.Each root in four connecting rods 52 all is a rod-shaped elements, has smooth basically external peripheral surface, but and each through hole that is used to receive connecting rod 52 on second dynamic pressure plate 26 all have sliding bearing sleeve 42.
Connector 28 is identical with connector 28 among the 4th embodiment, but and provides two connectors 28 in the position near each dynamic pressure plate 20,26 center.The bar 28b of each connector 28 holds (Fig. 5 A) but is secured on second dynamic pressure plate 26, it comprise expansion-head 28a (Fig. 5 A) but the other end be received in the staged through hole 62 of first dynamic pressure plate 20, but so it with along axis of guide 18a movably mode be attached on first dynamic pressure plate 20 (Figure 10).
Be understood that to have characteristic effect that the clamping 80 of above-mentioned configuration had identical with the clamping 70 of the 4th embodiment basically.In addition, in clamping 80, guide post 18 separates with connecting rod 52.Therefore, but might prevent that strain or distortion on the connecting rod 52 are passed to first dynamic pressure plate 20, thereby but improve and suppress the effect that first dynamic pressure plate 20 tilts or rotates, but this has further stablized the translation translation in other words of first dynamic pressure plate 20.And, also might further prolong the life-span of ball spline structure.
Figure 12 A-14 has provided the described clamping 90 of the 6th example of realizing second notion of the present invention.But make first and second dynamic pressure plates dorsad the biasing member of resilient bias except having, the configuration of the configuration of the clamping 90 of the 6th embodiment and the clamping 70 of the 4th embodiment is basic identical.Therefore, corresponding parts are represented with identical Reference numeral, and detail is described also no longer repetition.
Clamping 90 comprises the stationary platen 14 that is installed on the base 12; But first dynamic pressure plate 20 that can settle movably along the axis of guide 18a of guide post 18 with respect to stationary platen 14; Have the ball spline structure and but first dynamic pressure plate 20 is bearing in supporting structure 24 on the guide post 18 movably along axis of guide 18a; But but second dynamic pressure plate 26 that separates with first dynamic pressure plate 20 and can settle movably along axis of guide 18a with respect to stationary platen 14; But but to interconnect the connector 28 of first dynamic pressure plate 20 and second dynamic pressure plate 26 along the relatively-movable mode of axis of guide 18a; But but but but and be inserted between first dynamic pressure plate 20 and second dynamic pressure plate 26 and make first dynamic pressure plate 20 and second dynamic pressure plate 26 along the axis of guide 18a biasing member 92 (Figure 13) of resilient bias dorsad.
Shown in Figure 12 A and 12B, biasing member 92 is made of the flexible member of compression helical spring and so on, but makes first and second dynamic pressure plates 20,26 resilient bias dorsad in the position of connector 28.In embodiment as shown in the figure, but be provided for two connectors 28 (Figure 13) respectively near the position at dynamic pressure plate 20,26 centers by two biasing members 92 that compression helical spring constitutes.
But but an end of each biasing member 92 leans against second dynamic pressure plate 26 on the surface of first dynamic pressure plate 20, and but its other end is received in the female type hole 62d of portion of the staged through hole 62 on first dynamic pressure plate 20, but the opening part from through hole 62 over against second dynamic pressure plate 26 is absorbed in it, thereby the bar 28b of sealing connector 28, so biasing member 92 is set to the bar 28b around connector 28.Therefore, but but biasing member 92 make first dynamic pressure plate 20 with respect to second dynamic pressure plate 26 to the direction of stationary platen 14 skew (shown in arrow β).
When but but second dynamic pressure plate 26 closely contacts with first dynamic pressure plate 20 shown in Figure 12 A (corresponding to matched moulds state shown in Figure 13), biasing member 92 is pressed into the female type hole 62d of portion of staged through hole 62, thereby but makes the direction skew of first dynamic pressure plate 20 along arrow β.From this state, but when first and second dynamic pressure plates 20,26 towards end frame 32 when moving, but first and second dynamic pressure plates 20,26 enter the state (Figure 12 B) that is separated from each other by the effect of the connector 28 that illustrated.Under this state (corresponding to the described die opening state of Figure 14), the expansion-head 28a of connector 28 leans against on the shoulder face 62c of staged through hole 62, thereby but but second dynamic pressure plate 26 and first dynamic pressure plate 20 are fixed on predetermined tram, therefore biasing member 92 also is pressed in the female type hole 62d of portion of staged through hole 62, thereby but makes the direction skew of first dynamic pressure plate 20 along arrow β indication.
With reference to Figure 14, but but when driving toggle unit 44 so that second dynamic pressure plate 26 and first dynamic pressure plate 20 along die sinking direction (shown in arrow α) when mobile, but second dynamic pressure plate 26 at first begins to move towards end frame 32 at the supporting lower edge of sliding bearing structure connecting rod 18.Thus, but first dynamic pressure plate 20 by " gap " that obtain by connector 28 but be connected on second dynamic pressure plate 26, and keep static, but up to second dynamic pressure plate 26 move with described " gap " corresponding distance till.When but the distance that moves when second dynamic pressure plate 26 surpasses described " gap ", but first dynamic pressure plate 20 then begins to move towards end frame 32 at the supporting lower edge of the supporting structure 24 with ball spline structure connecting rod 18, also be subjected to the promotion of connector 28 simultaneously, thereby mould 17,22 is opened.
In this, but but in the time limit of the moment that moment to the first dynamic pressure plate 20 that moves since second dynamic pressure plate 26 begins to move, but biasing member 92 makes first dynamic pressure plate 20 towards stationary platen 14 resilient bias continuously.In addition, but pass through connector 28 during but second dynamic pressure plate 26 moves at first dynamic pressure plate 20, but biasing member 92 makes first dynamic pressure plate 20 towards stationary platen 14 resilient bias continuously.Therefore, but the unconscious instability that might effectively suppress first dynamic pressure plate 20 move, otherwise, but this situation may be caused by the behavior of being separated from each other of first and second dynamic pressure plates 20,26.
Be understood that to have characteristic effect that clamping 90 tools of above-mentioned configuration are had identical with the clamping 70 of the 4th embodiment basically.In addition, in clamping 90, but biasing member 92 is used to make first and second dynamic pressure plates 20,26 resilient bias dorsad, but therefore might prevent the irregular operation of first dynamic pressure plate 20 reliably.Therefore, but first dynamic pressure plate 20 can be stablized in the die sinking process and translation translation in other words smoothly, but and can not be subjected to the strain of second dynamic pressure plate 26 and/or the influence of inclination, therefore but but might highly precisely keep collimation between mould attaching surface 14a, the 20a of the stationary platen 14 and first dynamic pressure plate 20 and the collimation between stationary mold 16 and the dynamic model 22, thereby prolong the life-span of ball spline structure.
It is pointed out that clamping 60 (Fig. 6) and clamping 80 (Figure 10) can adopt above-mentioned biasing member 92.In this configuration, but the instability of first dynamic pressure plate 20 moves and also is certain to be solved.In addition, but the female type hole portion that is used for accepting biasing member 92 can be formed on second dynamic pressure plate 26.
Figure 15 A-17 has provided the described clamping 100 of the 7th embodiment that realizes second notion of the present invention.But make first and second dynamic pressure plates in opposite directions the biasing member of resilient bias except providing, the configuration of the configuration of the clamping 100 of the 7th embodiment and the clamping 70 of the 4th embodiment is basic identical.Therefore, corresponding parts are represented with identical Reference numeral, and detail is described also no longer repetition.
Clamping 100 comprises the stationary platen 14 that is installed on the base 12; But first dynamic pressure plate 20 that can settle movably along the axis of guide 18a of guide post 18 with respect to stationary platen 14; Have the ball spline structure and but first dynamic pressure plate 20 is bearing in supporting structure 24 on the guide post 18 movably along axis of guide 18a; But but second dynamic pressure plate 26 that separates with first dynamic pressure plate 20 and can settle movably along axis of guide 18a with respect to stationary platen 14; But but to interconnect the connector 28 of first dynamic pressure plate 20 and second dynamic pressure plate 26 along the relatively-movable mode of axis of guide 18a; But but but but and be inserted between first dynamic pressure plate 20 and second dynamic pressure plate 26 and make first dynamic pressure plate 20 and second dynamic pressure plate 26 along the axis of guide 18a biasing member 102 (Figure 16) of resilient bias in opposite directions.
Shown in Figure 15 A and 15B, biasing member 102 is made of the flexible member of compression helical spring and so on, but makes first and second dynamic pressure plates 20,26 resilient bias in opposite directions in the position of connector 28.In embodiment as shown in the figure, but be provided for two connectors 28 (Figure 16) respectively near the position at dynamic pressure plate 20,26 centers by two biasing members 102 that compression helical spring constitutes.
But each biasing member 102 is received in the bigger 62d of hole portion of the diameter of the staged through hole 62 on first dynamic pressure plate 20, and the one end leans against on the shoulder face 62c of staged through hole 62, and the other end leans against on the expansion-head 28a of corresponding connector 28, so biasing member 102 is set to the bar 28b around connector 28.Therefore, but but biasing member 102 makes first dynamic pressure plate 20 with respect to the direction skew (as arrow γ shown in) of second dynamic pressure plate 26 to end frame 32.
When but but second dynamic pressure plate 26 closely contacts with first dynamic pressure plate 20 shown in Figure 15 A (corresponding to matched moulds state shown in Figure 16), biasing member 102 is pressed into the bigger 62a of hole portion of diameter of staged through hole 62, thereby but makes the direction skew of first dynamic pressure plate 20 along arrow γ.From this state, but when first and second dynamic pressure plates 20,26 to end frame 32 when moving, but first and second dynamic pressure plates 20,26 enter the state (Figure 15 B) that is separated from each other by the effect of the connector 28 that illustrated.Under this state (corresponding to the described die opening state of Figure 17), biasing member 102 also is pressed in the bigger 62a of hole portion of the diameter of staged through hole 62, but, thereby but work to reduce space between first and second dynamic pressure plates 20,26 so that make first dynamic pressure plate 20 along the skew of the direction of arrow γ.
With reference to Figure 17, but but when driving toggle unit 44 so that second dynamic pressure plate 26 and first dynamic pressure plate 20 along die sinking direction (shown in arrow α) when mobile, but second dynamic pressure plate 26 at first begins to move towards end frame 32 at the supporting lower edge of sliding bearing structure connecting rod 18.Thus, but first dynamic pressure plate 20 by " gap " that obtain by connector 28 but be connected on second dynamic pressure plate 26, but but under the effect of the elastic bias force of biasing member 102 to 26 skews of second dynamic pressure plate.Therefore, but second dynamic pressure plate 26 move with described " gap " corresponding distance before, but first dynamic pressure plate 20 moves towards end frame 32 in 18 beginnings of the supporting lower edge of the supporting structure 24 with ball spline structure connecting rod, is subjected to the promotion of connector 28 simultaneously, thereby mould 16,22 is opened.
Like this, but but in the time limit of the moment that moment to the first dynamic pressure plate 20 that moves since second dynamic pressure plate 26 begins to move, but and first dynamic pressure plate 20 by connector 28 during but second dynamic pressure plate 26 moves, but but biasing member 102 makes first dynamic pressure plate 20 towards second dynamic pressure plate, 26 resilient bias continuously.Therefore,, moves the bias force of dependence biasing member 102 but might effectively suppressing the unconscious instability of first dynamic pressure plate 20, otherwise, but this situation may be caused by the behavior of being separated from each other of first and second dynamic pressure plates 20,26.
Be understood that to have characteristic effect that the clamping 100 of above-mentioned configuration had identical with the clamping 70 of the 4th embodiment basically.In addition, in clamping 100, but biasing member 102 is used to make first and second dynamic pressure plates 20,26 resilient bias in opposite directions, but therefore might solve the irregular operation of first dynamic pressure plate 20 reliably.In addition, biasing member 102 also is used to solve small the retreating (backlash) of connector 28, otherwise this situation can produce owing to the expansion-head 28a of connector 28 and being in contact with one another of shoulder face 62c of staged through hole 62.Therefore, but first dynamic pressure plate 20 can be stablized in the die sinking process and translation translation in other words smoothly, but and can not be subjected to the strain of second dynamic pressure plate 26 and/or the influence of inclination, therefore but but might highly precisely keep collimation between mould attaching surface 14a, the 20a of the stationary platen 14 and first dynamic pressure plate 20 and the collimation between stationary mold 16 and the dynamic model 22, thereby prolong the life-span of ball spline structure.
It is pointed out that clamping 60 (Fig. 6) and clamping 80 (Figure 10) can adopt above-mentioned biasing member 102.In this configuration, but the instability of first dynamic pressure plate 20 moves and also is certain to be solved.
Figure 18 and 19 has provided the described clamping 110 of the 8th embodiment that realizes second notion of the present invention.Except providing two biasing members that are provided at respectively in the clamping 90,100 92, outside 102, the configuration of the configuration of the clamping 110 of the 8th embodiment and the clamping of the 6th and the 7th embodiment 90,100 is basic identical.Therefore, corresponding parts are represented with identical Reference numeral, and detail is described also no longer repetition.
Clamping 110 comprises the stationary platen 14 that is installed on the base 12; But first dynamic pressure plate 20 that can settle movably along the axis of guide 18a of guide post 18 with respect to stationary platen 14; Have the ball spline structure and but first dynamic pressure plate 20 is bearing in supporting structure 24 on the guide post 18 movably along axis of guide 18a; But but second dynamic pressure plate 26 that separates with first dynamic pressure plate 20 and can settle movably along axis of guide 18a with respect to stationary platen 14; But but to interconnect the connector 28 of first dynamic pressure plate 20 and second dynamic pressure plate 26 along the relatively-movable mode of axis of guide 18a; But but but and the biasing member 100,102 (for example, along opposite direction) that is inserted between first dynamic pressure plate 20 and second dynamic pressure plate 26 and makes first and second dynamic pressure plates 20,26 distinguish dorsad and be offset in opposite directions along axis of guide 18a.
With reference to Figure 19, but but when driving toggle unit 44 so that second dynamic pressure plate 26 and first dynamic pressure plate 20 along die sinking direction (shown in arrow α) when mobile, but second dynamic pressure plate 26 at first begins to move towards end frame 32 at the supporting lower edge of sliding bearing structure connecting rod 18.Thus, but first dynamic pressure plate 20 by " becoming flexible " of obtaining by connector 28 but be connected on second dynamic pressure plate 26, but but under the effect of the reverse elasticity bias force of biasing member 92,102, be in elasticity " drift " state with respect to second dynamic pressure plate 26.Therefore, but second dynamic pressure plate 26 move with described " become flexible " accordingly apart from before, but first dynamic pressure plate 20 moves towards end frame 32 in 18 beginnings of the supporting lower edge of the supporting structure 24 with ball spline structure connecting rod, is subjected to the promotion of connector 28 simultaneously, thereby mould 16,22 is opened.
Like this, but but in the time limit of the moment that moment to the first dynamic pressure plate 20 that moves since second dynamic pressure plate 26 begins to move, but and first dynamic pressure plate 20 by connector 28 during but second dynamic pressure plate 26 moves, but but biasing member 92,102 makes first dynamic pressure plate 20 with respect to second dynamic pressure plate, 26 continuous elasticity " drift ".Therefore, move but but the elastic bias force that relies on biasing member 92,102 not only might effectively suppress the unconscious instability of first dynamic pressure plate 20 that may be caused by the behavior of being separated from each other of first and second dynamic pressure plates 20,26, but but and the unconscious instability that might effectively suppress first dynamic pressure plate 20 that may cause by the mutual conflict behavior of first and second dynamic pressure plates 20,26 during translation move.
Be understood that the clamping 110 with above-mentioned configuration has the characteristic effect substantially the same with above-mentioned clamping 90,100, but also have the advantage of two kinds of clampings 90,100.
It is pointed out that the driving force that the elastic bias force of biasing member 92,102 need be adjusted to, thereby do not influence the matched moulds operation of mould 16,22 less than drive part 30.In addition, biasing member 92,102 also can with other flexible members outside the spring for example rubber make.
When reference specific preferred embodiment explanation was of the present invention, those of ordinary skills were understood that and can make various changes and modifications to the present invention, and did not exceed the protection domain of thought of the present invention and following claim.
